Abstract: In an improved process for the pre-purification of air upstream of its introduction into a cryogenic air separation unit water vapour and carbon dioxide are removed from air by a pressure swing adsorption (PSA) process utilising an adsorbent which has an initial layer of activated alumina comprising from about 70% to 100% by volume of the bed with the remaining layer, if present, being a suitable zeolite. The particles of adsorbent, particularly the zeolite, have a particle size not greater than 2mm. Two beds (A,B) or adsorbent are employed. While one bed produces purified air, the other is vented to the atmosphere and then purged by impurity free gas to regenerate it. Both regeneration steps involve flow of gas through the bed countercurrent to the air flow during the production step. After purging, the bed being regenerated is repressurised by being fed (at its product gas end) product gas from the other bed.

Abstract: The cotter pin (5) for locking of bolts and shafts (1), particularly in agricultural machines, has a pivotable retaining clip (7) which is secured, in the closed state, against loosening. The locking is provided by the retaining clip (7) being passed through a hole (11) which is incorporated in the end (9) of the cotter pin (5). Provided on the retaining clip (7) is a step (13) on which there rests a helical spring (15) which loops around the retaining clip (7). At the other end, the helical spring (15) rests on the end (9) of the cotter pin (5). A hook-shaped or comb-shaped retaining part (17), which engages into a recess (19) on the end (9), is provided on the retaining clip (7) on the opposite side to the spring (15). In order to release the retaining clip (7), the latter is displaced in the hole (11) against the force of the spring (15) or is rotated in the anticlockwise direction until the retaining part (17) comes to rest outside the recess (19) and permits the pivoting of the retaining clip (7). <IMAGE>

Abstract: The invention relates to a spacing member arranged between a securing element (fixture) (13) implanted in the facial bone (the cranium) and an extraoral prosthesis, in particular a facial prosthesis. The spacing member comprises a base portion (1) intended to cooperate with the upper portion of the securing element (13), and an extension part (8,8') which forms an attachment point for the prosthesis (11). The extension part (8,8') is designed in such a way that it permits attachment of the prosthesis in a direction (10a,10a') (attachment direction) which forms essentially a right angle to the longitudinal direction of the extension part (8,8'). The spacing member combines the two conflicting requirements which exist particularly in the case of an orbital prosthesis, namely secure anchoring in the bone (radial attachment of the securing elements) and a more favourable attachment direction (10a,10a') (axial) for the prosthetic work.

Abstract: An assay device (14) for measuring the concentration of a soluble analyte, such as HDL-associated cholesterol, in a fluid sample containing interfering compounds, such as LDL- or VLDL-associated cholesterol, which can be selectively precipitated. The device includes a sieving matrix (26) capable of separating soluble and precipitated material migrating through the matrix, and a reservoir (34) which holds a precipitating agent which is effective, within a given concentration range, to selectively precipitate the interfering compounds. The reservoir is designed to delay the release of agent, on contact with the fluid sample, to maintain the concentration of precipitating agent in contact with the fluid sample within the given concentration range. The device additionally includes an assay pad (64, 66, 68, 70) in which the soluble analyte present in the fluid sample can be assayed. A method of separating high-density lipoproteins (HDL) from low- and very-low-density lipoproteins (LDL and VLDL) employs a coated glass fiber matrix which inhibits binding of HDL as a blood fluid sample containing HDL and precipitated LDL and VLDL passes through the matrix. <IMAGE>

Abstract: Le procédé et le dispositif décrits permettent d'estimer indirectement de façon quantitative les caractéristiques de la pression artérielle d'un sujet et des paramètres physiologiques variables similaires, grâce à l'utilisation de techniques indirectes non invasives. Ce procédé consiste: (i) à générer une séquence de signaux dont le caractère quantitatif dépend du paramètre variable; (ii) à transmettre et à traiter ces signaux à l'intérieur d'un système d'ordinateur et d'un réseau neuronal associé capables de générer un signal de sortie unique pour les signaux d'entrée combinés; (iii) à déterminer de façon invasive une valeur effective pour le paramètre conjointement à la génération non invasive de signaux des étapes précédentes; (iv) à appliquer des facteurs de pondération à l'intérieur du réseau neuronal au niveau des noeuds d'interconnexion, pour obliger le signal de sortie du réseau neuronal à correspondre à la vraie valeur du paramètre tel qu'il a été déterminé de façon invasive; (v) à enregistrer les signaux d'entrée, les facteurs de pondération et la vraie valeur sous la forme de données d'apprentissage à l'intérieur de la mémoire de l'ordinateur; et (vi) à répéter les étapes précédentes jusqu'à constituer suffisamment de données d'apprentissage pour permettre au réseau neuronal d'estimer avec précision la valeur des paramètres lors de la réception ultérieure de signaux d'entrée en ligne. On décrit également des techniques permettant la classification préalable de signaux et le rejet des artéfacts. Grâce à l'apprentissage fait au niveau du réseau neuronal, toute mesure invasive ultérieure est superflue et le système est prêt pour les applications diagnostiques et pour l'estimation non invasive des valeurs des paramètres.

Abstract: Disclosed is an image forming device in which a long photosensitive member (F) is sequentially transported from a supply section (5) along a transport path (6) to an exposure section (4), a heat developing section (7) and a pressure transfer section (8), a latent image is formed on the photosensitive member by exposure to an input image in the exposure section (4), the latent image is heat developed in the heat developing section (7) and the developed image is then transferred to a transfer member (P) in the pressure transfer section (8). In order to maintain the transport speed of the photosensitive member (F) constant in the exposure section (4), to prevent the transport speed downstream from the exposure section (4) from affecting the transport speed in the exposure section (4), and to absorb slack in the photosensitive member (F), a main transport means (72, 76, 103) for transporting the photosensitive member along the transport path (6) is disposed in the pressure transfer section (8). This facilitates achieving an accurate, smooth transport of the photosensitive member F with a simple configuration.

Abstract: A satellite communication system for providing maximum power output in a spread spectrum signal transmission is disclosed. Spectral shaping is provided at a satellite transmitter (Q) to shape a spread spectrum so that over a bandwidth of interest, the spectrum has a maximally flat characteristic. By maximizing the spectrum amplitude flatness, the required bandwidth power density limitation imposed to prevent interference with other communication facilities is maintained. In each earth station (10) receiving the transmission from the satellite, filtering of the demodulated baseband satellite signal is provided such that the spectrum is restored to its original shape. The filters (31,32) on the receive side may be analog, having the same amplitude-frequency function as the transmitter spectrum shaping filter, but having an inverse phase response. This ensures a matched filter condition at transmitter and receiver, maximizing signal transfer. A programmable demodulator (35) is provided to select a demodulation mode. The programmable demodulator may receive microcode from a microprocessor (36) configuring the PLA into a despreader demodulator (35) for spread spectrum applications or into a straight BPSK demodulator where the data signal has not been subject to spectrum spreading.
